.trinite To @ZZ whom t may concern Be it known that li, l'lnie'irr l. linerinirig a citizen of the United States oli America, re* :siding at New Britain, llarttord County, Connecticut, have invented a new and neetul lillectric Switch, ot which the tollowing' is a specification.

lli/ly invention relates particularly to what are commonly termed enap switches or quiclebreak switchen. Devices oit this kind rely upon a spring to throw the envite-h contact when motion has; been Started by hand or finger operation. tlonietin'iee the parte ot euch switches stick and they tail to act properly. ln order to overcome this dithiculty l provide a connection between the operating lever and the switch contact carrying arm, so that the switch arm 1e positively moved betere time 'for the automatic Spring action.

Figure 1 is a eide view and partial eec- 'tion 03E one form ot evvitch embodying` the improvements ot my invention;

lilig. 2 is e traneverse sectional 'view ot the switch mechanism proper;

llig. 3 is e eide view ot' the saine on e somewhat larger scale7 allowing` en exteneion ot the operating; lever;

ltig. 4t ie a perspective view ot the member `which carries the removable ewiteh contact;

:nld

itin'. 5 ie a perspective View o'l': the operatH ing member.

The switch proper has e traine "i" which is Secured to a Suitable ineulatiim4 Support 8, for instance, by means ot one or more screws 9. A switch Contact member is indicated by dotted lines at 10, though this invention doce not relate tothe particular it rm or arrangement of contacts.v The movable contact member is suitably supported by an erin 11, which preferablv has two eeinifcircular bosses 12y which are pivoted on the hub niembere 13 and may be pressed ont-- Wardly from the treme 7 as shown in my llatent No. 1 381,568.

'lhe operenng,` lever il; or tilting` plata has pivote 15, 15 :it oppoeite ei le suitebly enpported in the sides: et tl rthis plate 1 /1 also has one or incre projecting` lugs 1G, adapted to swing in a slot or elote 17 in the trame 79 the ends ot the slots servinn' as stops for the projecting luge '16. @ne oit the lugs 16 has a turther projecting lng 18, which is adapted to engage the pins 19 and 2O et the switch arm 11 when the inemw ber le is tilted on its,I pivote 15, 15.

The Spring; 21 interposed between the bottoni ot the switch arm 1 1 end the inner end ot the member 1l; tende to hold the Switch member against the lower part et the :trame 7, ne Shown in Fig. 3, or the upper part oli the treine,` ae ehown in 1. l.)reierabl},' the spiano@` 2l ie mounted on a rod 22, which is hooked onto one end oit' the member 111 end passes through a hole 23 in the switch member 11.

The tilting' plate or lever 14 may be opereted by mesme ot a rocker 211 and push but-` tons 25, es shown in Fig. 1, or by means of a lever, which n'iey have an insulating handle or linger piece, as indicated at 26 in Fig. 3.

lWhen the lever ie moved from the poeition ehoivn in Fig. 3, the lng 18 engages the pin 2O and Starte to move the switch ineinber 11 jnet betere the point ot connection between the member 141 and the rod pnssee the plane which containe the ance o t the hubs; 12 and the pivote 1,5. 'lhie etai-te a positive inoi'enu-nit o l'; the switch ineniber before the springbegins to exert ite Snap action. I the spring ineffective ie thus eliminated. lt claim: v
